Formed Outer Race Series SPB- Steel-on-Steel and Steel-on-PTFE Composite

Steel-on-Steel or PTFE composite, Formed Outer Race - Metric and Inch SeriesWhen the performance of a one piece outer ring is desired, AST has options in both Steel-on-Steel and Steel-on-PTFE Composite liners. Due to their one-piece design, these spherical plain bearings have smaller bore dimensions and depending on the series chosen range from 4 mm to 50 mm bores. Unlike most other spherical plain bearings, these are not fractured and subsequently do not have to be held together with rings or screws providing them with excellent load handling capabilities for their size. With both the Steel-on-Steel and the Steel-on-PTFE composite series, the outer ring is made of carbon steel and pressed around the inner ring.

Steel-on-Steel One-Piece Outer Ring Series

With this series, the outer ring made of carbon steel is pressed around the inner ring which is made of of carbon chromium steel, hardened, with a sliding surface treated with hard chromium plating. The outer ring has a groove and holes for lubrication, the inner ring is hard chrome plated. Since it is steel on steel, these spherical plain bearings must be properly lubricated with grease. AST supplies these in both inch and metric dimensions:

  • GEBJ_S Series – Steel-on-Steel, One-piece formed outer ring, Metric dimensions
  • GEFZ_S Series – Steel-on-Steel, One-piece formed outer ring, Inch dimensions

Steel-on-PTFE-Composite Liner One-Piece Outer Ring Series

With this series, the outer ring made of carbon steel is also pressed around the inner ring; however, the inner ring’s sliding surface is made of a PTFE composite material. The inner ring itself is made of carbon chromium steel, hardened, with its sliding surface treated with hard chromium plating. Since these spherical plain bearings have a PTFE composite liner and a hard chrome plated ball, lubrication is not recommended. Also, due to the PTFE composite liner, the bearing must be protected from dirt and contamination. AST Bearings has 75 different Formed Outer Race Spherical Plain Bearings to choose from including:

  • CE_C Series – Steel-on-PTFE-Composite, One-piece formed outer ring, metric dimensions
  • GEBJ_C Series – Steel-on-PTFE-Composite, One-piece formed outer ring, metric dimensions, Wide Series
  • GEG_C Series – Steel-on-PTFE-Composite, One-piece formed outer ring, metric dimensions, High Misalignment Series
  • GEFZ_C Series – Steel-on-PTFE-Composite, One-piece formed outer ring, Inch dimensions
